TIMEFCONTROLLER FOR ELECTRIC C'EJ'RRENTS.

Specification ofLetters Patent.

Application filed November 18, 1913. Serial No. 801,709.

To all whom it may concern: Be it known that I, JACOB JoNEs, a citizenof the United States, residing at St.

Joseph, in the county of Buchanan and State of Missouri, have inventedcertain new and useful Improvements in Time-Controllers for ElectricCurrents, of which the following is a specification, reference being hadtherein to the accompanying drawing.

My invention relates to improvements in time controllers for electriccurrents, the objects of which are,-to provide a mechanism of thisclass, by the use of which, electric devices, connected therewith, shallbe intermittently energized at the ends of periods of time, ofpredetermined duration, for economizing in the use of electric energy. 1

Further objects are to so construct said controller that the same shallbe particularly adapted to the controlling of electric currents usedinenergizing electric exterminators, for killing pests.

Still. further objects are to provide a complete time controlledelectric unit which shall be durable, compact, and neat in appearance.

I attain these objects by the mechanism illustrated in the accompanyingdrawing, in which Figure 1 is a front view of the controller and of anelectrocuting device, connected therewith. Fig. 2 is a side view ofparts" seen in Fig. 1, looking toward the left. Fig.

'3 is an enlarged perspective view, in detail,

of a portion ofthe fixed electrodes.

Referring to Fig. 1,.on the base 1, are mounted the battery case 3,induction coil case 5, and front 6. In the upper surface of said frontrests the front end portion of clock case 7 which is secured on base 1in any suitable substantial manner, not

shown. In case 3 is placed the cell of dry battery 3, provided withprimary electric conductor 9, which connects said battery with electriccircuit interrupter 10, mounted over the front end of primary coil 11.One of the terminals 11' of said primary coil, is connected withinterrupter vibrator 10',

while the other terminal 11", of said coil, is connected with metalclock frame 12, by primary conductor 13. Metal minute hand 14 iselectrically connected with said clock frame, through the well knownmetal parts of the clock, not shown. Movable electrode 15 is secured onand carried by the free end of said minute hand, for contacting thefixed electrodes 8, 2, 4, 2, 8, and so on, in the order named. Saidfixed electrodes are arranged in the same consecutive order, around theentire outer edge of clock dial 16.

Referring to Fig. 3,- fixed electrodes 8 are formed on the inner edge ofelectrode ring 8, at such distances from each other, as adapts them tobe contacted by electrode 15, at intervals of eight minutes of time,while fixed electrodes 4 are formed in the same manner, on electrodering 4:, and are so placed that they bisect the spaces betweenelectrodes 8. Fixed electrodes 2 are similarly formed onelectrodejr'ing- 2*, but are of such frequency, that they bisect thespaces between electrodes 8 and 41'. Said electrode rings haveinsulation 17 between them, and have their outer edges and surfacescovered by insulation-17'. The thus built-up groups of electrode ringsare secured together by the sheet metal binder 18, crimped thereon, andare secured on clock dial 16, (see Fig. 1), by screws 19, formed ofnonconducting substance such as hard rubber, fiber or the like. Saidfixed electrode rings are respectively connectedwith the elasticcontroller electrodes 8, 1, and 2, by conductors 8 4 and 2 The metalcontroller bar 20, provided with thumb lmob 20,is slidably mounted inbase 1, and is adapted to he slid out of and into contact with saidelastic electrodesJ Said bar is normally in contact with elasticelectrode 21, connected by conductor 22 with battery,

and since said parts may be of any well known form, the same are onlypartially shown and described. I

\Vhere brevity is hereinafter required, said parts collectively, will betermed a transformer.

In the exterminator, seen in Fig. 1, roller 24 is either formed of orcovered with any good insulating material. Said roller is rigidlymounted on brackets 25, secured at 25" on any desired fixed object, notshown.

Said brackets have hooks 25 formed on their lower ends, in which theends of catchtrough 26 are detachably held. The high potential nakedelectrocuting wires 27 and 28, are tightly wound on roller 24, inalternated spirals. The left end of wire 27 is connected-with secondaryterminal 23, by conductor 27 while the right end of wire 28 is connectedwith secondary terminal 23" by wire 28'. Said wires are properly to bythe feet of a fly 29, standing thereon; I In installation and operation,the operator of the exterminator, places the described parts in thepositions shown and despaced scribed, then by thumb knob 20, he slidesbar 20 11111311 said knob is even'with point 8, with said bar in contactwith electrodes 8 and 21, for energizing the electrocutin wires 27 and28, intermittently at'the en of. each period of eight minutes of time;but should he desire a two minute period of time, he slides said buttoneven with point 2. Should said operator desire that said period of timeshall be four minutes, he slides said thumb button even with point 4: asshown in Fig. 1. Said operator then winds and starts the described clockin the usual manner, by parts neither shown nor described.

When minute hand 14; carries movable electrode 15 into contact withfixed electrode 8, (as shown,) the primary circuit from battery 3' isclosed through the following conductors. From said battery throughconductor rupter vibrator 10', primary terminal '11, primary coil 11,primary terminal 11", conductor 13, clock frame 12, minute hand 14,movable electrode 15, fixed electrode 8, ring 8*, (see Fig. 3,)conductor 8", elastic electrode 8, controller bar 20, elastic electrode21,

- and thence through conductor 22, back to battery 3'. The thus closedprimary circuit conducts the primary electric current from said batterythrough said primary coil, until electrode 15 is carried by minutehandtl, from contact with electrode 8', which opens said circuit untilthe same is again closed, as

hereinafter described. While said primary coil is thus energized, thesame induces a high potential secondary electric current of electricity,through the described secondary electric circuit :Secondary coil23,secondary terminal 23, conductor 27 electrocuting wire 27, fly 29, wire28, conductor 28', and

thence through secondary terminal 23", back to secondary coil 23.

It will be understood that battery 3' gencrates a current of suchpotential energy, as

delivers a secondary current of'such energy,

that fly 29 is electrocuted thereby. When said electric impulse hasceased, said fly gravitates intocatch-trough 26. When desired, saidoperator liftssaid trough from be trod upon, at the same time,

9, interrupter 1 O, interedges of hook's 25, and empties the same of thethus electrocuted flies, and returns said trough to the position shown.

While controller bar 20 is in the position described and shown, it willbe seen that elastic electrode 2, is not in contact therewith, andtherefor understood, that fixed electrode -.2 is dead, and that movableelectrode 15 is carried into and from contact therewith, without closingthe previously described electric circuit or causing any electricimpulse, in any of the described parts.

When electrode 15 is carried into contact with fixed electrode 4, thepreviously de-' scribed primary circuit is again closed, but the same isdone through said fixed electrode and its described connections withelastic electrode 4. Since said fixed electrodes have two minute spacesbetween them, it is evident that when knob 20 is slid even with point.2, bar 20 is in contact with all three of the elastic electrodes andthereby electrifies all of the fixed electrodes around dlal 16. Whilesuch is done, movable electrode 15 closes the previously describedprimary circuit at each and every contact with said fixed electrodes, atthe end of each two minutes of time. I

When there is no fly .29 on wires 27 and 28', the described secondarycircuit is thereby left open, and counter electromotive force therebycaused to be generated in'primary coil 11, retards the action of battery3', thereby economizing in the use of its electric energy.

When bar 20 is slid towardthe left, to the limit of its movement, thesame is removed from contact with all of the previously describedcontroller electrodes, and the electric devices of the controller, standidle;
